AI Overview
GPS and Inertial Navigation Systems (INS) are integrated
to combine the high-frequency, drift-free, but noisy positional updates of GPS with the low-drift, high-stability short-term accuracy of INS, typically via an
Extended Kalman Filter (EKF)
. This fusion improves accuracy, reliability, and continuity, especially in GPS-denied or degraded environments.
Key Aspects of GPS/INS Integration:
- Complementary Strengths: INS provides continuous navigation data, while GPS corrects the long-term drift (error accumulation) inherent in inertial sensors.
